摘　　要：针对蒸汽这种高温高压介质的流量计,常规便携式超声波流量计无法进行现场在线比对,而对于一些因企业生产原因无法拆除计量器具,计量器具的量值经常无法进行检定或者校验溯源。该文建议性地提出一种蒸汽流量计在线比对方法,在不需要蒸汽管道停运放空的条件下,完成蒸汽流量计的现场在线比对;并对符合比对要求的某种插入式流量计从原理、构造到应用做了一些简单介绍。For the flowmeter of the high-temperature and high-pressure medium such as steam,the conventional portable ultrasonic flowmeter can not be made an on-site online comparison,while for some measuring instruments that can not be removed due to production reasons of enterprises,the measurement value of measuring instruments often cannot be calibrated or verified for traceability.This paper suggests an online comparison method of steam flowmeters,which completes the on-site online comparison of steam flowmeters without the shutdown and venting of the steam pipeline,and briefly introduces the principle,structure and application of a plug-in flowmeter that meets comparison requirements.
